So whats better a $70 serge protector or a $300 one If the ped gets hit by lighting no protector is gonna protect it right???
Forum Discussion
The only true protector is a saturated harmonic voltage transformer (volts control via hertz) followed by a true isolation transformer.
Incredibly expensive
Wastes power, develops heat
I had to design and make my own lightning protection circuit.
Did it work?
The structure had been isolated with an eight inch knife switch.
Lightning struck the 127 volt neighborhood feeder circuit then backfed and blew the 35 KW wye wound transformer.
The strike melted the pair of 8 gauge wires feeding the house. It melted 2 ¼" spaced copper plates and destroyed a 6 AWG shunt wire to earth ground.
Utilities protect transmission lines with devices called "reclosers". They cause a few seconds blackout after a line strike, then reclose.
I've made dozens of circuit protection devices for friends using 20mm MOV devices plus 5 amp avalanche rectifiers. Each parallel six times line to neutral to earth ground. All protected with rice grain fuses. It's not inexpensive.
For harmonic voltage control SOLA brand has been around a long time.
